Disco 2 FPR pipe unscrewed from cylinder head

Well, it’s happened again, this time from the cylinder head end, last time from the FPR. The diesel slick behind and the diesel stink made me think something may be wrong!! Luckily I was only a road from home and just got into the drive. The power steering gave up from all the diesel on the belt. The alternator has had a thorough diesel-wash.

So, the pipe FPR had unscrewed completely from the head. Why?? As far as I know it has been on there for 21 years and I haven’t disturbed it. I nipped it up and jumpered R1, the fuel pump relay, and there are no leaks. I was wondering how to stop this happening again. As I don’t know why it happened in the first place this is not easy. I was thinking of putting some threadlock on the threads being careful to avoid it mixing with diesel, but any suggestions welcome.

Thanks.

I have to agree. I would do exactly as you suggest. Cleaning up the threads both internal and external before whacking on some Loctite.

Very best of luck with it, Mate!
